MK 38 - 25 mm Machine Gun System
The MK-38 is a 25-mm machine gun installed for ship self-defense to counter High Speed Maneuvering Surface Targets (HSMST).
The MK 38 MOD 0 25mm MGS replaced the MK 16 20mm gun system and was then later upgraded to a MK 38 MOD 1 MGS. A total of 387 MK 38 MOD 1 MGSs were procured and deployed in the U.S. Navy and U.S. Coast Guard (USCG). In 2003, the chief of Naval Operations (CNO) directed the Navy to pursue a simple, stabilized, low cost solution for outfitting near-term deployers to counter small boat threats. The Navy began fielding the Mk 38 MOD 2 in 2005. Due to the success of the MK 38 MOD 2 MGS, the program scope was expanded in July 2012 to add several ship classes and to develop a modification to the system. This modification is known as the MK 38 MOD 3 which is a technical refresh of the MK 38 MOD 2. The first MK 38 MOD 3 is to be fielded in FY17. As of 2016, 307 MK 38 MOD 2 systems have been delivered. There are 50 MK 38 MOD 3s on contract. The total POR is for 517 systems.
Installed aboard CG, CVN, DDG, FFG, LSD, LPD, LHD, LHA, LCC, MK VI, PC, OSV and USCG FRC class ships and planned for installation aboard AS and USCG offshore patrol cutter (OPC) class ships, the MK 38 MGS is a low cost, stabilized self-defense weapon system that dramatically improves ships' self-defense capabilities.
